i SANDING DEVICE FOR AUTOMOBILES.

Specification of Letters Patent.

Patented Sept. 29,1914.

Application filed November 14, 1913. Serial No. 800,986.

tomobiles and similar vehicles to discharge fine gravel, dry,vcoar se sand or a similar dry, non-packing material onto a roadway immediately in front of the bottom portion of the tires of the rear or drive wheels to prevent the vehicle from skidding on a slippery roadway.

In order to accomplish the desired result use is made of a container adapted to contain a dry, non-packing material, such as fine gravel, coarse sand and the like, a dis charge pipe extending from the said container in a rearward direction, a sleeve mounted to slide on the rear end of the discharge pipe and terminating in a nozzle normally closed by a valve, manually-controlled means for imparting a slidingmotion to the said sleeve, and automatic means for automatically opening and closing the said valve on imparting a sliding motion to the said sleeve. Use is also made of means for shiftably and removably securing; the container in position on the under side of the running board to allow of conveniently filling the container with fine gravel or other non-packing material.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the vlews.

Figure 1 is a side elevation of the sanding device as applied to an automobile and with the bottom of the body shown in section; Fig. 2 is an enlarged sectional side elevation of the same; Fig. 3 is a similar view of a portion of the same and with the similar vehicle, and the said container A is adapted to contain fine gravel or dry, coarse sand or a similar dry non-packing material, tobe delivered by the device, presently to be described in detail, onto a roadway immediately in front of the lower portions of the tires of the rear or drive wheels I? of the automobile. The container A is open on top and is provided with a hoppershaped bottom A connected at its lower end with a pipe C extending rearwardly and slightly curved in a rearward and down ward direction, as plainly indicated in Figs. 2 and 3.

On the pipe C is mounted to slide'a sleeve D terminating at its rear end in a nozzle D,

preferably flattened in a transverse direction, as plainly indicated in Fig. 5, and the said sleeve D is mounted toslide in a suitable bearing E attached to the under side of the container A. The nozzle D is normally closed by a valve F pivoted at F on the topof the nozzle D and the said valve F is provided with an upwardlyextending arm F pivotally connected with a rod G extending forwardly and mounted to slide in a bearing H attached to the top of the sleeve D. The rod G is provided with spaced shoulders G 3 adapted to engage a stop piIi E forming part of hearing or bracket E. It will be noticed that when the sleeve D is in forward position on the pipe C, as show-n in Fig. 2, then the valve F is in closed position and the shoulder G is adjacent the stop pin E When the sleeve D is moved rearwardly, as here inafter more fully described, then the rod G is carried along and its shoulder G finally moves in engagement with the stop pin vE so that on further rearward movement of the sleeve D the rod G exerts a pull on the arm F to swing the valve F. into open position, as shown in Fig. 3.

In order to impart a sliding movement to the sleeve D the following arrangement is made: The sleeve D is pivotally connected at its front end by a forwardly-extending rod or pitman I with a crank pin J on an arm J 2 secured to a crank shaft J extending transversely and-journaled in. suitable bearit will be noticed that the rods I of the two sanding devices on the running boards B are connected with the arms J 2 on the same crank shaft J so that when the latter is rocked a simultaneous rearward or forward sliding movement is given to both sleeves D of the two sanding devices. The crank shaft J is provided at or near its middle with a crank arm J 3 pivot-ally connected by a link K with the lower end of a pedal lever L fulorumed at L on a bracket E attached to the under side of the bottom B of the body of the automobile, as indicated in Fig. 3. The upper end of the pedal lever L extends through an opening B in the bottom B so that the upper end of the said lever L is within convenient reach of the foot of the chauffeur or other person in charge of the automobile. A spring N is attached at one end to a bracket A formed on a reinforcing plate A held on the under side of the container A, and the other end of the said spring N is attached to the link or pitman I to normally hold the sleeve D in the re tracted position shown in Figs. 2 and 5. When the chauffeur imparts a swinging motion to the pedal lever L then a rocking I110- tion is given to the shaft J whereby each of the rods I of the two sanding devices is moved rearwardly .to impart a rearward sliding movement to the corresponding sleeve D. The sleeve D in moving rearwardly also moves downwardly so that its nozzle D is in close proximity to the roadway immediately in front of the corresponding rear or drive wheel B of the automobile. When the sleeve D moves into rearmost position the valve F is opened, as previously explained, to allow the gravel or coarse sand to pass out of the nozzle D onto the roadway in front of the rear or drive wheel B It is understood that during the rearward movement of the sleeve -D the spring N is placed under tension, and when the operator releases the pedal lever L then the several parts return to the normal posi-' tion shown in Figs. 1, 2 and 5,

It will be noticed that the material contained in the container A passes by its own gravity into the pipeC and along the same into the forward end of the sleeve D held closed at the time by'the valve F. As the material is in the form of gravel or dry, coarse sand it is evident that it readily passes from the container A through the pipe G into the sleeve D to fill the front end of the latter especially as suflicient vibration is given to the parts mentioned while the vehicle isrunning to accomplish the desired result, that is, to fill the pipe C and the forward end of the sleeve D with the contents of the container A. When the operator presses the pedal lever L, as previously mentioned, the sleeve D is caused to slide rearwardly and the valve F is opened so that the material contained in the sleeve D readily passes out through the nozzle D and down onto the roadway in front of the rear or drive wheel B to prevent the latter from skidding on a slippery roadway. When the operator releases the pressure on the lever L the sleeve D slides forward as previously explained and its rear end is again gradually filled with the material contained in the pipe C owing to the incline of the latter and the vibration given to the pipe C incident to the running of the automobile.

Itis understood that fine gravel or coarse sand readily rolls along in the pipe C and the sleeve D without danger of packing in the said pipe or the sleeve, and hence when the sleeve D is pushed rearwardly and the valve F is opened therein the material readily rolls out of the nozzle D down onto the roadway. By using fine gravel or coarse, dry sand a firm adhesion is had between the peripheral face of the rear or drive wheel B and the roadway to prevent the automobile or similar vehicle from skidding on a slippery roadway. It is understood that when the sleeve D is in normal retracted position it is a sufficient distance above the roadway to clear obstructions in the roadway and consequently the parts of the sanding device are not liable to be damaged. When the sleeve D is pushed rearwardly and downwardly its nozzle D is sufiiciently close to the roadway to properly scatter the gravel or coarse sand on the roadway immediately in front of the tire of the rear or drive wheel B to insure proper adhesion of the said wheel on the roadway with a view to prevent skidding.

Each container A is preferably mounted to slide transversely on guideways O attached to the under side of the corresponding running board B so that each container can be drawn out partly to permit of conveniently filling the container with fine gravel or coarse, dry sand. The running board B normally covers the open top of the container A, and the container A is normally fastened in place by screw rods P held on the outer ends of the guideways O and engaging the outer side A of the container A. lVhen it is desired to slide the container A outward the nuts P of the screw rods P are unscrewed to unfasten the container A and to allow of drawing the same outward for filling purposes.

The outer side A of each container A is extended at the ends and bottom to act as a protector for the sanding device. It will be noticedthat the pipe C, sleeve D, valve F and rods G and I are supported by and move with the container A when the latter is shifted transversely for filling purposes or is entirely removed from the machine.

The rod I has a detachable connection with the pin J to permit of temporarily disenaging the said rod I from the pin J when drawing the container out for filling the same or when removing the sanding device from the automobile. The pedal leverL, link K and crank shaft J may or may not be removed when detaching the container and th'parts c arried thereby from the machine. The rear of the container is provided'with a recess A for accommodatingthe pipe vC,'sleeve D and rod G thus permitting the use of a long container to hold a large quantity of gravel or sand and at the same time support the said pipe 0, sleeve D and rod G.

The sanding device shown and described is very simple and durable in construction and composed of comparatively few parts, not liable easily to get out of order. It will also be noticed that the sanding device can be readily applied to -,automobiles and similar machines now generally constructed.
